POWDER-DISPENSING DEVICE Application filed December 26, 1930. SerialITO/504,789. I

My invention relates to powder-dispensing devices intended for generaluse but especially well adapted for dispensing powdered soap and has forits object the provision of such a device that is simple inconstruction, easy to operate, positive in its action, and when closed,protects the contents of the container from dust, dirt and moisture andprevents waste of the powder during the dispensing thereof. Moisture inthe container often causes the powder to become lumpy and thusinterferes with the operation of the device. I

To the above end, generally stated, the invention consists of the noveldevices and combinations of devices hereinafter described and defined inthe claims.

In the accompanying drawing, which illustrates the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawing:

Fig. 1 isa view partly in side elevation and partly in central verticalsection; and

Fig. 2 is a View in transverse section taken on the line 2-2 of Fig. 1.

The numeral 0 indicates a powder-dispensing cylindrical container havinga dis placeable cover 1 and a bottom 5 in the form of an invertedtruncated cone with a gravity feed discharge opening 6 at its apex.

Within the container 3 is a frame 7 formed from a single metal strapbent to form a pair of diametrically opposite side members, which bearagainst the sides of said container, and upper and lower cross-tiemembers. This frame 7 is detachably but rigidly secured to the container3 by screws 8. The lower end portions of the side members of the frame 7are in converging relation and rest on the bottom of the container 3with the lower cross-tie member within the bottom of the container.

The passageway 6 is normally closed by a valve 9 which is below the apexof the bottom of the container 3 and arranged to seat thereon whenclosed. This valve 9 has at its axis an upwardly projecting squarestem10 .which extends axiallyinto the container 3 through the passageway6 andapertures' in the upper and lower members of the frame I? :5 withfreedom for compound endwise and rotary. movement. A coiled spring ,11encircling the valve stem 10,between the crosstie members of theframe/7, is anchored at its lower end of the lowermost of said members@155 and attached at its upper end tothe stem 10. This stem 10 alsoextends axially through a relatively. fixed depending sleeve '12 on theupper cross-tie member ofthe frame'7 with freedom for endwise andturningmove- 3 ments Formed in the sleeve ,12 is a-spiral groove or channel 13and cooperating therewith is a fixed cam stud 14 on the stem 10. Thevalve 9 is constructed'andarranged to open and close by acompound-endwise and 1,65

rotary movement imparted thereto by the cam device 13-14. Thespring'llnormallyholds the valve 9 closed and which valve is pro videdat its lower'end with a radially projecting handle 15 by which it may beturned 10 .to cause the cam= device1314 to vmove the valve 9 axiallydownward to open the same. A depending spout 16 is secured to the bot-.tom of the container 3 in axial alignmentwith .the passageway 6 andradially spacedtherefrom and the valve 9. This spout 16 terminates abovethe handle 15 so as to not inter- 'ferevwith the action thereof. The topof the valve 9, which closes the passageway 6, is

spherical and facilitates the escape of the F powder-from the'container3 through the discharge passageway 6 when-said valve is open.

A second valve 17 on thevalve stem 10 and 1 in the form of a disk isvertically spaced above; the main valve This valve 17 isconstructed 3and arranged to open and close in reverse 7 y comprisingtwo pairs ofcircumferentially spaced rods that project upward parallel to the wallsof the bottom of the'container 3 and spaced therefrom. The two' pairs ofagitator rods 18 are secured at their lower ends to the valve-stem atvertically spaced points and the valve 17 is held thereby against axialmovement on said stem. Formed in the pe riphery of the valve 17 areV-shaped notches 19 through which the agitator rods 18 of the lower pairextend.

Any suitable separable fastener may be provided formounting thecontainer on a Wall 4 or other relatively fixed support.

ieau'se-the c'am device'1314to close the valve From the abovedescription it is evident that by means of the handle'15 the valve9, andhence its stem 10, may be turned iniafdi-n rection to cause the camdevice 1314"to" positively move the valve 9,-down-ward'iand open thesame to allow the powder between wise and turning movements, a cam pinon the valve stem extending into the cam slot,

the valves 9 and 17 to flow through 'the 'passageway 6 and be directedby the spou'tdownw'ard into a handheldjthereunden At the completion ofthe opening move- -ment of the valve '9 the valve 17 will close' andprevent further flow of powder from thereabove. I Upon releasing thehandle 1'5 the spring 11, which was-tensioned by the openingof the valve9, will lift said valve and i'a't'the same time turn the same andthereby 9zan'd open the valve I During the rotation of-the valve '9 theagiita'tor rods .18 are turned about the axis ofthe stem 10 and "therebykeep the powder Iloose ;so that the same will. freely flow between thebottdmofythe container 3fand the valve 117 and over the valve 9 andthrough the dis-V charge passagewayfi.
